Apneic Tracheostomy in COVID-19 Patients on Veno-Venous Extracorporeal Membrane Oxygenation.

COVID-19 creates an impressive burden for intensive care units in terms of need for advanced respiratory care, with a huge number of acute respiratory distress syndromes (ARDS) requiring prolonged mechanical ventilation. In some cases, this proves to be insufficient, with a refractory respiratory failure calling for an extracorporeal approach (veno-venous ECMO). In this scenario, most of these patients need an early tracheostomy procedure to be carried out, which creates the risk of distribution of aerosol particles, possibly leading to personnel infection. The use of apneic tracheostomy has been proposed for COVID-19 patients, but in case of ECMO it may produce lung derecruitment, severe hypoxemia, and sudden worsening of respiratory mechanics. We developed an apneic tracheostomy technique and applied it in over 32 patients supported by veno-venous ECMO. We present data showing the safety and feasibility of this technique in terms of patient care and personnel protection. Gas exchange and pH did not show statistically significant changes after the tracheostomy, nor did respiratory mechanics data or the need for inspiratory pressure and FiO2. The use of apneic tracheostomy was a safe option for patient care during ECMO and reduced the possibility of virus spreading.

Dynamic arterial elastance measured with pressure recording analytical method, and mean arterial pressure responsiveness in hypotensive preload dependent patients undergoing cardiac surgery: A prospective cohort study.

BACKGROUND: Organ perfusion is a factor of cardiac output and perfusion pressure. Recent evidence shows that dynamic arterial elastance is a reliable index of the interaction between the left ventricle and the arterial system and, in turn, of left ventricular mechanical efficiency. A practical approach to the assessment of dynamic arterial elastance at the bedside is the ratio between pulse pressure variation and stroke volume variation, which might predict the effect of a fluid challenge on the arterial pressure in patients undergoing cardiac surgery. OBJECTIVE: To evaluate the ability of dynamic arterial elastance, measured by the pressure recording analytical method (PRAM), to predict the response of mean arterial pressure (MAP) to a fluid challenge. DESIGN: Prospective observational study. SETTING: Cardiac surgery patients in a university hospital. PATIENTS: Preload-dependent (pulse pressure variation ≥13%), hypotensive (MAP ≤65 mmHg) patients, without right ventricular dysfunction, at the end of cardiac surgery. INTERVENTIONS: A 250 ml fluid challenge infused over 3 min. MAIN OUTCOME MEASURES: A receiver-operating characteristic curve was generated to test the ability of the baseline (before fluid challenge) dynamic arterial elastance (primary endpoint) and all other haemodynamic variables (secondary endpoint) to predict MAP responsiveness (≥10% increase in MAP) after a fluid challenge. RESULTS: Of 270 patients undergoing cardiac surgery, 97 (35.9%) were preload-dependent, hypotensive and received a fluid challenge. Of these 97 patients, 50 (51%) were MAP responders (≥10% increase in MAP) and 47 (48%) were MAP nonresponders (<10% increase in MAP). Baseline dynamic arterial elastance (mean ±â€ŠSD) had an area under the curve of 0.64 ±â€Š0.06 [95% confidence interval (CI), 0.53 to 0.73; P = 0.017]. A dynamic arterial elastance at least 1.07 with a grey zone ranging between 0.9 and 1.5 had 86% sensitivity (95% CI, 73 to 94) and 45% specificity (95% CI, 30 to 60) in predicting MAP increase. CONCLUSION: In a hypotensive preload-dependent cardiac surgery cohort without right ventricular dysfunction, dynamic arterial elastance measured by PRAM can predict pressure response for values greater than 1.5 or less than 0.9.

Identification of a Circulating miRNA Signature to Stratify Acute Respiratory Distress Syndrome Patients.

There is a need to improve acute respiratory distress syndrome (ARDS) diagnosis and management, particularly with extracorporeal membrane oxygenation (ECMO), and different biomarkers have been tested to implement a precision-focused approach. We included ARDS patients on veno-venous (V-V) ECMO in a prospective observational pilot study. Blood samples were obtained before cannulation, and screened for the expression of 754 circulating microRNA (miRNAs) using high-throughput qPCR and hierarchical cluster analysis. The miRNet database was used to predict target genes of deregulated miRNAs, and the DIANA tool was used to identify significant enrichment pathways. A hierarchical cluster of 229 miRNAs (identified after quality control screening) produced a clear separation of 11 patients into two groups: considering the baseline SAPS II, SOFA, and RESP score cluster A (n = 6) showed higher severity compared to cluster B (n = 5); p values < 0.05. After analysis of differentially expressed miRNAs between the two clusters, 95 deregulated miRNAs were identified, and reduced to 13 by in silico analysis. These miRNAs target genes implicated in tissue remodeling, immune system, and blood coagulation pathways. The blood levels of 13 miRNAs are altered in severe ARDS. Further investigations will have to match miRNA results with inflammatory biomarkers and clinical data.

Efficacy and Safety of Fibrinogen Concentrate in Surgical Patients: A Meta-Analysis of Randomized Controlled Trials.

OBJECTIVES: To investigate the efficacy and safety of fibrinogen concentrate (FC) in surgical patients. DESIGN: Meta-analysis of randomized controlled studies (RCTs). SETTING: Perioperative. PARTICIPANTS: Adult and pediatric surgical patients. INTERVENTIONS: A search of PubMed/Medline, Embase, Cochrane Central Register of Controlled Trials, Transfusion Evidence Library, Google Scholar, and the proceedings from major international anesthesiology meetings up to February 1, 2016 for RCTs that compared FC with placebo or other comparators. MEASUREMENTS AND MAIN RESULTS: The primary outcome was all-cause mortality. Pooled risk ratios and mean differences (MDs) were computed with either fixed-effects or random-effects models. The study included 14 RCTs comprising 1,035 patients; the majority of patients underwent cardiac surgery. All-cause mortality was lower in the fibrinogen group (4/432 [0.9%] v 15/430 [3.5%]; risk ratio 0.26; 95% confidence interval [CI] 0.09-0.78; p = 0.02; heterogeneity statistic (l2) = 0%). The use of FC was associated with reduced bleeding (MD -127 mL; 95% CI -207 to -47; p = 0.002; I2= 54%) and a lower number of red blood cells units transfused versus comparator (MD -0.9; 95% CI -1.3 to -0.5; p<0.001; I2 = 42%). There were no differences in the rates of thrombotic events and myocardial infarction. CONCLUSIONS: In surgical patients, FC was associated with reduced bleeding and a lower number of red blood cell units transfused, and it also might reduce mortality. However, none of the analyzed trials was powered for estimation of survival and adverse events with FC use. Half of the included studies were of high or moderate risk of bias. The evidence primarily came from cardiac surgery settings.

Esophageal papilloma: Flexible endoscopic ablation by radiofrequency.

Squamous papilloma of the esophagus is a rare benign lesion of the esophagus. Radiofrequency ablation is an established endoscopic technique for the eradication of Barrett esophagus. No cases of endoscopic ablation of esophageal papilloma by radiofrequency ablation (RFA) have been reported. We report a case of esophageal papilloma successfully treated with a single session of radiofrequency ablation. Endoscopic ablation of the lesion was achieved by radiofrequency using a new catheter inserted through the working channel of endoscope. The esophageal ablated tissue was removed by a specifically designed cup. Complete ablation was confirmed at 3 mo by endoscopy with biopsies. This case supports feasibility and safety of as a new potential indication for Barrx(TM) RFA in patients with esophageal papilloma.

Costs of laparoscopic and open liver and pancreatic resection: a systematic review.

AIM: To study costs of laparoscopic and open liver and pancreatic resections, all the compiled data from available observational studies were systematically reviewed. METHODS: A systematic review of the literature was performed using the Medline, Embase, PubMed, and Cochrane databases to identify all studies published up to 2013 that compared laparoscopic and open liver [laparoscopic hepatic resection (LLR) vs open liver resection (OLR)] and pancreatic [laparoscopic pancreatic resection (LPR) vs open pancreatic resection] resection. The last search was conducted on October 30, 2013. RESULTS: Four studies reported that LLR was associated with lower ward stay cost than OLR (2972 USD vs 5291 USD). The costs related to equipment (3345 USD vs 2207 USD) and theatre (14538 vs 11406) were reported higher for LLR. The total cost was lower in patients managed by LLR (19269 USD) compared to OLR (23419 USD). Four studies reported that LPR was associated with lower ward stay cost than OLR (6755 vs 9826 USD). The costs related to equipment (2496 USD vs 1630 USD) and theatre (5563 vs 4444) were reported higher for LPR. The total cost was lower in the LPR (8825 USD) compared to OLR (13380 USD). CONCLUSION: This systematic review support the economic advantage of laparoscopic over open approach to liver and pancreatic resection.

Internal Delorme vs. STARR procedure for correction of obstructed defecation from rectocele and rectal intussusception.

PURPOSE: "Outlet obstruction" is a complex functional disorder compelling patients to exhausting uneffective attempts to void. This study was designed to compare the effectiveness and a safety of the endorectal proctopexy (internal Delorme) vs STARR procedure in two groups of patients. METHODS: A total of 66 patients with rectocele and associated mucosal prolapse or anorectal intussusception between January 2006 and June 2010 were randomly assigned to Group # 1 Endorectal proctopexy with levatorplasty (ERPP) and Group # 2 STARR. Patients were assessed one week, six and twelve months after the operation. Operative time, postoperative pain, day of discharge and late complications was recorded. The time of recovery of work was also assessed. The continence score was updated with a constipation questionnaire. Quality of life after the operation and the overall grade of satisfaction were assessed and compared with radiological findings. All patients were reassessed after one year. RESULTS: The results in the two groups of patients show no significant difference between ERPP and STARR: the improvement in symptoms is similar but significant and well definite in both groups with a low incidence of postoperative complications. STARR procedure is just faster to perform even if more expensive. Dyspareunia slightly improved mainly in ERPP group, due probably to scar distention. CONCLUSION: The results of our experience indicate a significant improvement of symptoms with both techniques. The overall incidence rate of postoperative complications is low and similar between the two groups. As economical consideration, ERPP is less expensive.

Axillary lymphadenectomy for breast cancer in elderly patients and fibrin glue.

BACKGROUND: Axillary lymphadenectomy or sentinel biopsy is integral part of breast cancer treatment, yet seroma formation occurs in 15-85% of cases. Among methods employed to reduce seroma magnitude and duration, fibrin glue has been proposed in numerous studies with controversial results. METHODS: Thirty patients over 60 years underwent quadrantectomy or mastectomy with level I/II axillary lymphadenectomy; a suction drain was fitted in all patients. Fibrin glue spray were applied to the axillary fossa in 15 patients; the other 15 patients were treated with harmonic scalpel. RESULTS: Suction drainage was removed between post-operative Days 3 and 4. Seroma magnitude and duration were not significant in patients receiving fibrin glue compared with the harmonic scalpel group. CONCLUSIONS: Use of fibrin glue does not always prevent seroma formation, but can reduce seroma magnitude, duration and necessary evacuative punctures.

Long term quality of life after laparoscopic antireflux surgery for the elderly.

BACKGROUND: Studies have previously shown laparoscopic antireflux surgery is a safe and effective treatment for GERD even in elderly patients. The aim of the current study was to evaluate patients receiving laparoscopic antireflux surgery before and after 65 years of age and to assess their surgical outcomes and improvements in long term quality of life. METHODS: Patients were given a standardized symptoms questionnaire and the Short-Form 36 Health Survey for quality-of-life evaluation before and after laparoscopic total fundoplication. RESULTS: Forty-nine patients older than 65 years of age were defined as the elderly group (EG) whereas the remaining 262 younger than 65 years of age were defined as the young group (YG). CONCLUSIONS: In conclusion, laparoscopic total fundoplication is a safe and effective surgical treatment for gastroesophageal reflux disease generally warranting low morbidity and mortality rates and a significant improvement of symptoms comparable. An improved long-term quality of life is warranted even in the elderly.

Conservative versus surgical treatment for chronic anal idiopathic fissure: a prospective randomized trial.

Anal fissure is a tear in the lining of the anal canal distal to the dentate line, which most commonly occurs in the posterior midline. Anal fissure was defined chronic if the patient presented with history of anal pain during defecation for at least 2 months with the observation of sphincter fibers at the base of the lesion. One hundred and forty-two consecutive patients with a chronic anal fissure with hypertonicity of internal sphincter on proctological examination were selected for this study from October 2008 to October 2010. Patients enrolled for the study were randomized to two groups by using a computer-generated list. Patients who underwent lateral internal sphincterotomy (LIS) were operated as day surgery procedures under local or epidural anesthesia. Patients randomized to conservative treatment were prescribed to use warm anal dilator with a nifedipine ointment 5 min twice daily for 4 weeks. Patients were clinically examined after 2, 4 and 8 weeks of treatment to evaluate if there was complete healing of the fissure. All patients were required to record pain after the first defecation, on 3rd and 7th postoperative day on a self-administered VAS scale in cm (0-10). Sixty-eight patients were randomly assigned to LIS, 74 to the conservative approach. Fifty-one patients of topical nifedipine group (68.9 %) and 60 patients of LIS group (88.2 %) presented an anal fissure healed at 8 weeks with a p value of 0.0077. As regards post-operative pain, 43 patients of LIS group (63.2 %) and 25 patients of topical nifedipine group (33.7 %) referred first defecation as painless. In the topical nifedipine group 43 (58.1 %) after 3 days since treatment and 35 (47.3 %) after 7 days had pain. In the LIS group 22 (32.3 %) after 3 days and 9 (13.2 %) after 7 days referred pain. There was no statistical difference between LIS and topical nifedipine group concerning side effects. Lateral internal sphincterotomy is an effective, less painful, fast recovery treatment for chronic anal fissure. Incontinence rate is overestimated and often the fear of a continence disturbance, albeit with a low incidence following surgery, may obscure the need to relieve symptoms which may be so severe as to make the patient's life intolerable.
